Application september 28,1931, serialNassaco'z y 4 Claims.

My invention relates to improvements in paper radiator shields,l and more particularly to a method of making the same to produce such shields which shall be neat andattractive in appearance, simple in construction and with the minimum amount of handling during the process of'manufacture, which may be made economically and speedily, and which shall be eiicient and satisfactory for use wherever found appli# cable. y 4

One of the principal objects of my invention is the production `of a radiator shield of the kind described, which may be folded to the radiator-conforming shape and which will retain its parts, and the methodemployed in the produc-- tion'of the same, as shown and described, and' more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts throughout the views,

Figure 1 is an elevation View of one of my shields ready for. placement upon a radiator; c Figure 2 shows a vertical sectionof the sam as mounted uponthe radiator; i

Figure 3 is a fragmentary perspective Viewr of the top portion of the shield;

Figure 4 is a plan view folding; and l y Figures 5-10 illustrate the various'stages of folding.

`Referring more particularly to the drawings, wherein I have illustrated a preferred embodiment of my inventiomR indicates a radiator of more or less standard type and construction, and upon which my shield or cover S is to be removably mounted. In carrying out my invention, I make these radiator shields or covers of` angularlyupwvardly'A flanges 3 *and l4 respectively of the blank, ready' for manufacture and in actual servioeas aradiator shield.

Such a sheet ofV paper is of generally rectan-v gular shape, and is marked or scored in any desired manner so as toffacilitate the folding op-I 5 erations thereupon. The shieldisformed of sufyfcient size toreceivethe *top portion of the radiator therein `and tofdepend downwardly there'- from, the'to'p of the shield being indicatedatA, and provided with a pair of-sidewalls-B-B'at itherfsidebf lthe radiator, and'with a .connect-f ing rear wall C, the sidewalls" beingjnarrower toward'V their bottom if desired; andas"shown.v 'v The top of the shield is providedwith a. downwardly extending flange along the-front edgeA of the'top, as at 1, thisvflange being'extended rearwardly at either side'as atf2--2,'ito thereby de-y ne the radiator'ereceiving vopening'. A'dustytrap is provided bythe inwardly directed and thence aty the lower--edgeof the front flangel 1.'4

' The shield is madeof a single sheet'of paper or `other similarly flexible andf'fcheapmaterial4 suitable forthe purpose, and the'isame'maylbe plain," "or may be' "colored,y decorated," .por otherv wise ornamented in any suitableman'ne "eitheri before orafter the forming thereof. 'l 'i This blank is 'of generally'rectangularsh pe or outline, with the top and bottom edge'su and- 7 respectively' -paralleL' and the latteredge pref-' erably slightly shorter.` than the topedge, inthe form shown :in the drawings; Y The'f'side.

1213, and.14, as indicated. These-may actually be .scored lines or otherwise indicated, for, thewpurpose of facilitating the foldinlgjof the` shield jduring'they malfzingV of the same. Each vof the upper corners of thesheetmay' be provided with a narrow `cut-,out v 15 indi,- cated byv the dotted lines therea't,i or the same,` lfunction maybe had by slitting thesheet for a short distance downwardly and; the l part -lil their bent by doubling the slitportio'ii orito'fthe'y sheet. Thissheet of paper is. preferably -laid'at uponsome Vsupporting plane and the lowerpo'rtion may then' be .bent back upon itself along theline 14,4 `thus vbringing the lower edge 'l adjacent the line 13, asshown in dotted lines in Fig. 5. r f

y' The topi'edger-of the sheet is then `brought NT oFFlol:l

down onto the body of the sheet by folding along the lines 10 and 12, in the direction opposite to the folding of the lower portion of the sheet, this folded portion along the line l0 forming the flange 4 of the dust trap. f

Each of the upper corners of the sheet is then folded toward one another, as shown in Fig. 6, along the diagonal lines of fold l6-l6, so as to bring the upper portions of the side edges 8-8 horizontal. Each of these corners is then lifted up, as shown in Fig. '7, so that the previously folded edges 10 will form an upstanding continuous channel or corner above the plane of the sheet, the ends of the channel coinciding with the lines of vertical Ifold 17--1'7 inwardly of the side edges of the sheet and parallel there- The next step consists in flattening the aforementioned upstanding channel, by folding the same onto the face of the sheet, as indicated in Fig. S, this folding at either end being along the top portion of the diagonal line 16.

They previously folded lower portion of the sheet is then folded diagonally along the lines 18f-18, this diagonal line of fold `intersecting the sideedge of the sheet a slight distance above the bottom of the previously folded upper portion of the side edge 8, the first fold along the diagonal lines 18 being indicated in Fig. 8 (at the right-hand side), and the second similar fold Lbeing completed and shown in Fig. 9, and

there is now a triangular tab defined between the lines of fold 17 and that portion projecting laterally to either side of the sheet and indicated at 5-e-5.

means maybe applied instead of the adhesivel hereinbefore mentioned, for securing the parts together.

.Due to `the fact that the diagonal lines of fold 18 extend above the bottom edge of the hori- ,zontally extended side edges 8 (seeFig. 8, lefthand side, also Figs. 6 and '1) the superimposed continuation of this vertical edge 8 will be above or past the tip or apex of the triangular tab (see right-hand side of Fig. 8). This superimposed edge'8 extends horizontally to the line 17 vat the base of the triangular tab and thence extends obliquely past and overlapping the lower free edge of the portionv 2 of the shield (see Fig. 8, right-hand side),

As hereinbefore stated, Athe adhesive is applied as indicated in the shaded areas of the tabs 5*-5, whereupon the tabs may be folded down until the adhesiveV has set. This is the only application of the. adhesive during the entire manufacture of the shield, and consequently there is little or no loss of time in waiting for the adhesive to dry before continuing with further operations of making the shield.

The vertically extending distance defining the area of the adhesive 20 is greater toward the base ofthe tab than adjacent the apex, so that the adhesive will cover only the desired surfaces,

and whereby thefront flange 1 and the dust trap flanges 4 and 3 will be freeofV securement to these tabs, so that the shield may be fully and properly unfolded for use when desired.

ln order to further compact the shield, the same is folded along the lines 13 and 21, and the lower tip then inserted beneath the front forming portion of the shield, as shown in Fig. 10. Thus the resultant product is neat and compact, and well adapted for shipping, storage, or other handling, and upon opening will present an attractive appearance for use uponaradiator.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, arrangement, construction and combination of parts herein shown and described or the 'method employed, except as limitedby the state of the artvto which this invention appertains, or the claims hereto appended.

What I claim as new and desire to secure by Letters Patent is:

1. The method of forming aradiator shield, comprising taking a substantially rectangular sheet of material and folding it on itself along the top edge; folding diagonally at each of the corners of said end to form triangular portions; folding said triangular portions to bring said uppermost fold into a yvertical plane; folding said last-mentioned edge downwardly along a line parallel to said top edge, while reefolding f the" upper upstanding edge along the first diagonal line of fold; folding diagonally from the bottom of the sheet to form tabs projecting lat- `erally at the sides of the top of said sheet; and

securingl the various parts of the shield together by securing said tabs against said previously folded portions.

2. The method of forming a paper radiator shield, comprising folding the top and bottom edges of the sheet parallel to one anotherv and in opposite directions; folding the upper corners diagonally inwardly toward one another to form triangular portions thereat; folding the upper portions of said triangular portions above the plane of the sheet and thence folding the same vlaterally downwardly along a diagonal line at each end; folding the lower corners of the folded sheet diagonally to overlap the triangular portions and form tabs; and then securing said tabs onto the previously folded down portions of the triangles and onto the adjacent portions of the diagonallyk folded lower corners;

3. The method of forming a paper radiator shield, comprising folding the top and the bottom of a rectangular sheet parallel to one another and in oppositedirections; folding the upper corners diagonally inwardly to form triangular portions; folding the upper portions of said tr-iangular portion above the plane of the sheet; folding said upstanding edge downwardly along aline parallel to the top line of fold, while re-folding said upper upstanding edge on said diagonal lines of fold; folding diagonally upwardly from the lower corners of the sheet, said diagonal lines of fold terminating above the lower edge of the triangular portions previously formed; applying adhesive to the tabs thus formed at either side, the adhesive area being shaped so as to be of lesser height adjacent the `'outer tips of the tabs than at the inner portions; and then folding the tabs inwardly toward one another. y f

e. The method of forming `a paper radiator shield, comprising folding the top and the bottom of a substantially rectangular lolank of paper along parallel lines and in opposite dreotions; folding the upper corners diagonally toward one another to form triangular portions; folding the upper portions of said triangular portion above the plane of the sheet; folding said upstanding edge downwardly along a line parallel to the top line of fold, While re-folding said upper upstanding, edge on said diagonal lines of fold; folding the lower corners diagonally toward one another to form triangular tabs projecting laterally of the blank, the last mentioned diagonal lines of fold terminating above increasing height toward thev base of said triangular tabs, and thence folding said tabstoward one another; and then folding and inserting the lower portion of the thus folded blank bel neath the previously folded portion.
